I am running manjaro on my raspberry pi 4, with KDE plasma. Got the official image and only did a pacman -Syu to get the latest updates.

KDE plasma version is 5.20.3
Framework 5.76.0
Qt 5.15.1
Graphic is V3D 4.2

My issue is that as soon as I try a download I get kicked out from the session. If I try to launch most apps I get kicked out. So basically as soon as I put a load on the system it kicks me out of the session and I need to login again. If I login and leave it, it runs for hours and nothing happens.

Sometimes I get an error report: plasmashell pid 4129 segmentation fault (11)

Any tip on how to troubleshoot or solve it is most welcome!

I tried to switch from 4K to 2k and so far it seems to be more stable. So if anyone else having issues it seems like switching res makes it stable.
